Customer Question

I have a Panasonic over the range Microwave . Model : NN-H275. Up until yesterday it worked fine. Now, Once you set the controls and push start it comes on for about two seconds and the promptly shuts off. I unplugged it and plugged it in again and I tried all other settings but nothing seem to work. What could be wrong?

Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond as typing, researching and adding links takes me time to do so please be patient and often I will ask you questions to narrow down the issue to get is diagnosed correctly.

If it shuts down right away you likely have an inverter board failure. The unit will try to start but if there is a failure or something shorted on the inverter board inside the unit that will happen. The cost to fix this is typically more than a new microwave so that is up to you to fix or not
